+- At least one IP address is required for each Edge host.
 - You must ensure that the Edge hosts have stable IP addresses. You have the following options to achieve stable IP
   addressing for Edge hosts:
+
   - Use static IP addresses. Contact your network administrator to assign the Edge host a static IP address.
   - Use Dynamic Host Configuration Protocol (DHCP) reservations to reserve an IP address in a DHCP network. Contact your
     network administrator to reserve IP addresses for your Edge hosts in a DHCP network.
   - Enable network overlay on your Edge cluster. Network overlay can only be enabled during cluster creation. For more
     information about network overlay, refer to [Enable Overlay Network](../networking/vxlan-overlay.md).
